HOG-FHNGER.

SPECIFICATION forming part of Letters Patent No. 757,054, dated April 12, 1904.

Application filed December 18, 1903. Serial No. 185,765. (No model.)

To all whom it may concern.-

Be it known that I, GLENN A. RoBINsoN, a citizen of the United States, residing at Geneseo, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Hog-Ringers; and I do de= clare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hog-ringers of that type comprising pivoted handles carrying jaws to grip and compress the ring to force it through the septum narium of the nostrils of the hog; and it consists of the peculiarities of construction hereinafter described and claimed.

The primary object of the invention is to provide in a device of this charactermeans for holding the jaws partially closed to grip the ring between them and to throw the jaws open upon the release of the handles after the ,ring has been applied, thus enabling the op erator to employ one hand and arm to hold the hog and the other hand to handle the tool without liability of the ring becoming disengaged from the tool and also enabling him to efiect the quick release of the tool after ringing the hog.

In the accompanying drawings, Figure l is a side view of a hog-ringer embodying my invention, showing in full and broken lines the different positions of the handles and jaws; and Fig. 2 is a section through a portion of the tool. showing features of the invention.

The form of tool herein shown is of a type in common use, modified for the application of the parts constituting the present invention. It consists, as shown, of handles 1 and 2, crossed and pivoted together after the manner of a pair of pliers, as at 3, and provided with the ring holding and compressing jaws I have shown in Fig. 1 of the drawings the normal position (denoted a) of the parts in full lines, the expanded condition of the parts (denoted by a) in dotted lines, the same representing the adjustment of the parts to admit a ring between the jaws, and the compressed condition of the parts (denoted a) in dotted lines, the latter illustrating the action of the handles and jaws in compressing the ring in applying the same to the nostrils of a hog.

In carrying my invention into practice I provide one of the handles of the took-say the handle 2with a lug or projection 6, extending from its inner side and form both handles with openings 7. Between the handles I interpose a coil-spring 8, which surrounds or seats at its lower end about the lug 6 and bears against the inner sides of the handles. The ends of the Wire composing this spring form attachingextensions 9, which are projected through the openings 7 and are bent or otherwise offset upon the outer sides of the handles to hold them in position. By this construction it will be observed that the expansive action of the spring upon the handles 1 and 2 causes the latter to be forced apart from the dotted-line position a to the full-line position a, thereby moving the jaws 4 and 5 from a compressed condition, which closes the ring,to the normal position, in which the closed contracted ring is automatically released. j

It is well known that in the use of the ordinary construction of ringers of this cliaracter the operation of ringing a hog is at all times rendered exceedingly difficult, for the reason that the operator is compelled to hold the jaws closed to grip the ring, which is frequently released under the struggles of the animal to free itself, thus compelling the operator in many cases to release the hog to recover and reapply the ring or to insertanew ring under difliculties while holding the hog. By my construction these disadvantages are overcome, as the jaws under the expansive pressure of the spring will hold the ring sufficiently firm to prevent its disengagement even in the event of the tool being knocked out of the hand of the operator while struggling with a fractious hog. The spring also by the mode of application herein shown performs a secondary function of restoring the parts to their normal position after the ring has been compressed and applied to the nostrils of the hog to release the grip of the jaws upon said ring, thereby enabling the tool to be quickly released. This function is attained the handles 1 and 2.

by the compression of the spring when the handles are forced together from the full-line position a to the dotted-line position a so that the reaction or expansion of the spring serves to force them apart again when the pressure is released to open the jaws to release the contracted ring. The spring, further, by its retractive action allows the jaws to be forced apart to receive a ring and then contracts and automatically partially closes the jaws to grip the ring upon the release of Thus in the operation of the tool the jaws are first opened to their widest extent to receive the ring a by spreading the handles 1 and 2 apart to the position 0/, whereby the spring 8 is expanded and upon the removal of spreading pressure upon the handles contracts, causing the jaws to grip the ring a before they are closed as far as the full-line position a. Then upon compressing the handles to position a the jaws will be forced to a greater extent toward each other and will contract and close the ring (4 this being the operation in applying the ring to the hogs nostrils. Such compressing action of the handles of course compresses the spring, which upon the removal of the pressure expands to the normal position (0 again, thereby opening the jaws to the normal extent and releasing the applied spring. Hence it will be seen that the spring is important in its applied relation, as it not only insures the firmretention of the open ring, but releases the closed ring upon the release of the pressure of the hand of the operator on the handles 1 and 2.

The ringer will hold any size open ring ready for use and will release any size of closed or contracted ring. A set-screw 10 of ordinary construction is mounted upon the jaw l and projects through the spring 8 and is adapted to engage the lug 6 to limit the closing movement of the handles and jaws to suit different set-screw 10, whereby the latter may be made shorter, so as to decrease the liability of its becoming broken in the operation of the tool.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. Ahog-ringer comprisingpivotedhandles provided with jaws,and a spring interposed between the handles and acting thereon by contraction to partially close the jaws to grip a ring, and ada )ted, when the handles are compressed, to close the jaws to compress and close a ring and by expansion to open the jaws when the handles are released, substantially as described.

2. A hog-ringer comprising pivoted handles provided with jaws, a lug upon one handle, a

coiled spring secured at its ends to the handles and surrounding said lug, and a set screw upon the other handle extending through the spring to engage said lug, substantially as described.

In testimony whereofI have hereunto set my hand in presence of two subscribing witnesses.
